Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
The description explains the main flow (returns real status, handles missing order) and explicitly states no fabrication. There is no output schema, so the description bears responsibility for return behavior, which it covers reasonably well. However, it does not specify the exact structure of the returned 'clear status', leaving slight ambiguity. Given the tool's simplicity, this is adequately complete for a 4.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
